Alan McNamara was jailed for life for the murder of Andrew ‘AOD’ O’Donoghue at in Limerick in June 2015

The shooting was in revenge for an incident the previous day, when three members of the Road Tramps punched him and took his waistcoat with a Caballeros patch sewn into it.

This exclusive security camera footage captures the moment Road Tramp motorcycle club members Raymond ‘George’ Neilon and Jim McCormack carry out what is considered to be the ultimate insult among the biker fraternity — publicly removing their rival’s motorcycle patches and jacket from him by force.

Their target, Alan ‘Cookie’ McNamara, of the rival Caballero MC, is left on the ground outside Kelly’s pub, in Doon, Co Limerick, after his patches are torn from him.

A third Road Tramp Seamus Duggan “restrained” McNamara’s wife Mary, during the robbery.

In a letter, he apologised to Mr O’Donoghue’s family. He wrote: “I’m sorry Andrew died. I will regret this for the rest of my life”.

McNamara’s stepson, Robert Cusack, 28, of Abington, Murroe, was jailed for six years with the final 18 months suspended, after pleading guilty to impeding McNamara’s apprehension, after he took possession of the murder weapon and hid it following the fatal shooting.

State Prosecutor Michael Collins told a sentencing hearing for the three Road Tramp members the robbery and murder were “interrelated”.

At a hearing last April, Limerick courthouse heard tensions were high between the Road Tramps and the Caballeros club.
